The light curve files have the following 3-column format:

Column 1 - the Heliocentric Julian date (HJD), minus 2400000

Column 2 - normalized r-band magnitude

Column 3 - magnitude uncertainty

Plots of the catalog light curves:

Both the phased light-curve/model plot (black dots: normalized observed magnitudes; blue curve: MECI model)
and the model residual plot (below) of each EB in the catalog are shown here.
The listed periods (P) are in units of days.

I. Eccentric [N=34]: EBs with unequally-spaced eclipses (PDF) (postscript)

II. Circular [N=290]: EBs with equally-spaced but distinct eclipses (PDF) (postscript)

III. Ambiguous-unequal* [N=103]: EBs with undetected secondary eclipses (PDF) (postscript)

IV. Ambiguous-equal* [N=103]: EB with equally-spaced and indistinguishable eclipses (PDF) (postscript)

V. Inverted** [N=23]: detached EBs that are not successfully modeled by MECI (PDF) (postscript)

VI. Roche-lobe-filling** [N=318]: non-detached EBs that are filling at least one Roche-lobe (PDF) (postscript)

VII. Unclassified Abnormal*** [N=20]: EBs with atypical out-of-eclipse distortions (PDF1 PDF2) (postscript1 postscript2)

  * These two groups contain the same EBs, where each binary in group IV is assumed to have twice the orbital period of the respective entry in group III. These systems are only counted once.

 ** The models of these EBs produce poor fits. We included them here for illustrative purposes only. We do not use their fitted parameters.

*** See Table 5 in paper for details. Note that all but five systems are modeled and classified in other groups.

Errata:

1. In the AJ paper, the labels of the final three light curves in panel 3 of Figure 11 (Eccentric EBs) should be:
T-Tau0-02487, T-Tau0-03916, T-UMa0-01822 (as written in Table 3).
This error had been corrected in the astro-ph listing.

2. Many of the targets in the Cas0 field have been listed with incorrect coordinates due to a bad match-up
with 2MASS sources. All the other fields should be OK.
Specifically, the coordinates of T-Cas0-00524 should read:
RA = 00:52:43.013
Dec = +50:28:10.20  (J2000)

This target is a known Algol-type eclipsing binary, identified as V364 Cas (among other identifiers; see SIMBAD).
